security-related TPM data. A local, unprivileged user could read the
results of a previous TPM command. (CVE-2011-1162)
Clement Lecigne discovered a bug in the HFS filesystem. A local attacker
could exploit this to cause a kernel oops. (CVE-2011-2203)

use this flaw to cause a denial of service if the system has an active
wireless interface using the b43 driver. (CVE-2011-3359)
